The 2 cryptic species of Euwallacea nr. fornicatus (Coleoptera: Curculionidae: Scolytinae) have more than 300 known hosts, of which avocado is the most important. Fusarium dieback, the fungal disease associated with these beetles, has killed some host plant species in Israel and the USA. Kuroshio shot hole borer, one of the 2 cryptic species, is reported for the first time in Baja California, Mexico, and represents a new threat to avocado and other potential hosts in urban and natural areas.
